The old culvert was installed in 1966.

The work will involve replacement of the steel culvert with a concrete pipe, necessitating a cut in the highway and a lane closure.

Motorists will encounter single-lane alternating traffic, likely directed by flaggers during the day and a signal at night, until the highway cut is closed. Then motorists can expect daytime single-lane alternating traffic until the project is completed in October.
